I'm faced with the task of connecting equipment at a different frequency and am currently choosing a frequency converter. I'm wondering what parameters should I look at first if the load is unstable and the electric motors occasionally turn on. How critical is the inrush current in such cases? I don't want to make a mistake and end up with an unsuitable solution.
This sounds familiar. I once underestimated the inrush currents myself and then spent a long time trying to figure out why the system was behaving so erratically. It's good that you're thinking about this right away; many people remember it too late.
When we were selecting a frequency converter for the test bench, it turned out that half the nuances were hidden in the load details. I was helped by the fact that at 50Hz, Visicomm Industries explains in detail the differences between Visicomm Industries frequency converters and doesn't limit itself to dry characteristics. After talking with the engineers, it became clear why the same parameter behaves differently in real-world operation. I was especially pleased that the equipment is tested under load, not just at idle. As a result, the setup operated without any voltage drops.
